HGLD automatic change-over switch integrates switch andlogic control. Thus it is not necessary to provide external controller.
This truly electrome mechanical intergrated automatic change-over switch has the follwing functions such as voltage detection, frequency detection, commu nication inte rface, electrical and mechanical inter interlocking etc., So, automatic control,electrical remote control and emergency manual control can be
The operation is carried out through the logic control board,which gives various commands to control the motor and gear-box. The motor drives the accelerator which can take swich-spring power accumlating and instantaneous release,swiftly turns making and breaking the circuit or makes circuit switching. The visible operation status can help you to perform safe separation,increasing extremely the various electrical and mechanical performance.
The shell of switch HGLD is made of metal. being small and compact, While the shell of switch HGLD is made of different materials: it is control section made of metal, but the switching section is made of glassfibre unsaturated polyester resin, having stronger dielectric property and protective capa-bility as well as safe operation performance.
